Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and safely elevated.
Disconnect the battery before starting work to prevent electrical issues.

2. Inspect and Replace Oil Filter

Sub-steps:
1. Locate the oil filter; remove it using an oil filter wrench.
2. Apply a thin layer of new engine oil to the O-ring of the new oil filter.
3. Install the new oil filter hand-tight, then tighten slightly with the wrench.

3. Change Engine Oil

Sub-steps:
1. Place an oil drain pan under the oil pan.
2. Remove the oil drain plug using a socket wrench (ensure to use a new gasket).
3. Allow the old oil to drain completely.
4. Replace the drain plug and tighten to the manufacturer-recommended torque (typically around 20-30 ft-lbs).
5. Fill the engine with new oil through the oil filler cap, using the correct type and amount (usually 4.5-5 quarts of 0W-20 or 5W-20).

4. Replace Oil Pressure Sending Unit (if necessary)

Sub-steps:
1. Locate the oil pressure sending unit; it is usually near the engine block.
2. Disconnect the electrical connector.
3. Use a socket to unscrew the old sending unit and install the new one.
4. Reconnect the electrical connector.

5. Final Checks

Sub-steps:
1. Reconnect the battery.
2. Start the engine and allow it to run for a few minutes.
3. Monitor for oil leaks and ensure the oil pressure light is off.
